This is a simple CAPTCHA based on ASIRRA project's idea.
User is presented with multiple images of different objects and must select images of correct type, such as dogs or cats.
Its a good choice for your forum because its not a standard CAPTCHA, so spam bots can't solve it yet, its easy to customize and its very friendly to visitors.

How to add/remove/customize image collections:
Go to directory library/PhotoCaptcha/Collections/. In that directory you will find sub-directories with collections of images. Add/remove images, edit collection.json (text file). Each image should be 200x160 pixels in jpg, png or gif format.
Images in default collections are mostly from random websites. Some might be copyrighted. I'll replace them with images that can be distributed later.
